## Arch Analysis – How to Analyse Determinate and Indeterminate Arches

Arches are one of the most efficient and elegant structural forms. Their efficiency has seen them selected throughout history as the go-to form for spanning large distances. In this tutorial, we’ll explore the different methods for analysing both determinate 3-hinge arches and indeterminate 2-hinge and fixed arches. Through worked examples, we’ll develop the various methods, with particular attention paid to how Virtual Work can help us unlock indeterminate arches. After completing this tutorial, you’ll have a better appreciation for the structural behaviour of arches, and you’ll be confident in analysing arch structures by hand!

## Building a Shear Force and Bending Moment Diagram Calculator in Python

In this project we’re going to build a Shear Force and Bending Moment Diagram calculator using Python in the Jupyter Notebook development environment. Generating the shear force and bending moment diagram for a simple beam with anything other than basic loading can be a tedious and time-consuming process. Once you finish this project, you’ll have a calculator that can produce shear force and bending moment diagrams at the push of a button.

## Shear and Moment Diagrams – An Ultimate Guide

Shear force and bending moment diagrams tell us about the underlying state of stress in the structure. Determining shear and moment diagrams is an essential skill for any engineer. Unfortunately it’s probably the one structural analysis skill most students struggle with most. So in this post we’ll give you a thorough introduction to shear forces, bending moments and how to draw shear and moment diagrams. By the end of this post you’ll know a lot more about shear forces and moment moments then when you started.
